CROSS-REFERENCE TO RELATED APPLICATION

This Non-Provisional Patent Application claims the benefit of the filingdate of U.S. Provisional Patent Application Ser. No. 61/011,022 filedJan. 14, 2008, entitled “LOW-PROFILE FLAT PANEL DISPLAY MOUNT.”

BACKGROUND

Panel displays include a display and a display mounting deviceconfigured to secure the display to a surface. Displays includeinformation panels, televisions, and/or monitors. Recently, flat paneldisplays have been developed having a space-saving depth of only a fewinches and designed to be attractively mounted on a wall in a home or anoffice. The known display mounting devices employed to mount these flatpanel displays are inconsistent with the space-saving design, and oftenhave a thickness that is greater than the thickness of the flat paneldisplay. In addition, to the limited degree that the conventionaldisplay mounting devices are adjustable, the adjustability is achievedat the expense of bulky mechanisms that further increase the thicknessof the mounting devices.

For these and other reasons, there is a need for the present invention.

DETAILED DESCRIPTION

In the following Detailed Description, reference is made to theaccompanying drawings, which form a part hereof, and in which is shownby way of illustration specific embodiments in which the invention maybe practiced. In this regard, directional terminology, such as “top,”“bottom,” “front,” “back,” “leading,” “trailing,” etc., is used withreference to the orientation of the Figure(s) being described. Becausecomponents of embodiments can be positioned in a number of differentorientations, the directional terminology is used for purposes ofillustration and is in no way limiting. It is to be understood thatother embodiments may be utilized and structural or logical changes maybe made without departing from the scope of the present invention. Thefollowing detailed description, therefore, is not to be taken in alimiting sense, and the scope of the present invention is defined by theappended claims.

It is to be understood that the features of the various exemplaryembodiments described herein may be combined with each other, unlessspecifically noted otherwise.

In this specification, the phrase “degrees of freedom” means the set ofindependent displacements and/or rotations that specify the displacementor position or orientation of a body. A body that moves inthree-dimensional space may have three translational degrees of freedomand three rotational degrees of freedom for a total of six degrees offreedom. Translation is movement without rotation, while rotation isangular motion about an axis.

The following definitions are taken relative to a wall defining an X-Yplane, with the X-axis oriented horizontally and the Y-axis orientedvertically, with a Z-axis extending out of the X-Y plane away from thewall:

In this specification, tilt means rotational movement about the X-axis.Tilt has the same meaning as pitch in nautical/mechanical terms.

In this specification, pan means rotational movement about the Y-axis.Pan has the same meaning as yaw in nautical/mechanical terms.

Tilt and pan are rotational movements.

In this specification, swing means movement along the X-axis (e.g.,movement left and right). Swing has the same meaning as sway innautical/mechanical terms.

In this specification, telescope means movement along the Z-axis (e.g.,movement forward and backward). Telescope has the same meaning as surgein nautical/mechanical terms.

Swing and telescope are translational movements.

In this specification, torque means a force employed to rotate anobject. Torque is analogous to the force employed to twist a shaft.

In this specification, braking torque means a resistance force impedingrotation of an object.

In this specification, differential braking torque is defined to be anon-zero difference between the braking torque for an object rotating ina first direction relative to the braking torque for the object rotatingin a second direction. For example, differential braking torque meansthat the braking torque for a shaft rotating clockwise is different thanthe braking torque for the shaft when it is rotating counter-clockwise.

In this specification, full range of motion for a display mountingdevice is defined to include at least four degrees of freedom includingtilt, swing, pan, and telescope degrees of freedom.

FIG. 1 is a perspective view of a display assembly 10 according to oneembodiment. Display assembly 10 includes a display 12 coupled to adisplay mounting device 14, where the display mounting device 14 isconfigured for attachment to surface, such as a wall W, for example, byany form of suitable connectors 16.

The display mounting device 14 includes shafts connected between panelsthat combine to enable the display 12 to be moved away from and betilted/extended from the wall W at nearly any desired orientation, forexample, through a combination of movements about (or relative to)shafts 28 and a tilting shaft 42. In one embodiment, at least one of theshafts 28, 42 is subject to a differential braking torque that allowseven large and heavy displays 12 to be selectively positioned in adesired orientation relative to wall W.

The display 12 includes electronic displays and non-electronic displays,such as photographs, paintings, and artwork. In one embodiment, thedisplay 12 is an electronic display, such as a television, a computermonitor, or other information display. In one embodiment, the display 12is a 50 inch Pro-101FD flat panel display that is about 9 mm thick andavailable from Pioneer Electronics, Tokyo, Japan. In general, largerdisplays will be heavier. The display mounting device 14 enables thecontrolled movement and placement of heavy/large displays away fromwalls to which the displays are attached.

FIG. 2 is a perspective view of the display mounting device 14 accordingto one embodiment. The display mounting device 14 includes a wallmounting assembly 20 that is attachable to a wall or other surface byconnectors 16, a panel mount assembly 22 configured to couple to thedisplay 12 (FIG. 1), and a link arm assembly 24 coupled between the wallmounting assembly 20 and the panel mount assembly 22. Movement of thepanel mount assembly 22 relative to the wall mounting assembly 20 isfacilitated by at least one of the shafts 28, 42 being subjected to adifferential braking torque.

In one embodiment, the wall mounting assembly 20 includes a wall bracket30 and an add-on bracket 32 that is coupleable to the wall bracket 30.In one embodiment, the wall bracket 30 and the add-on bracket 32 aregenerally planar members coupled together and attached to a wall thatthus defines an X-Y plane. As described herein, the X-axis is orientedhorizontally and the Y-axis is oriented vertically, with a Z-axisextending out of the X-Y plane away from the wall.

The wall bracket 30 is configured to be attached to a predetermined(measured) location on wall or other surface by the connector 16, andthe add-on bracket 32 is attachable to the wall bracket 30 by anysuitable fastening mechanism. In one embodiment, the wall bracket 30 isattached to a wall by connector 16, and a consumer or technicianconnects the add-on bracket 32 to the wall bracket 30 in a desiredlocation along the X-Y plane.

In one embodiment, the panel mount assembly 22 includes a tiltingbracket 40 coupled to the link arm assembly 24, a tilting shaft 42coupled to the tilting bracket 40 by a hinge 54 a, and panel brackets44, 46 coupled to the tilting shaft 42. It is to be understood thatalthough two panel brackets 44, 46 are illustrated, the display mountingdevice 14 can include a single panel bracket 44 or multiple panelbrackets.

In one embodiment, at least the tilting shaft 42 is selectively dampenedby an appropriate strap/bracket assembly described below that imparts adifferential braking torque to the tilting shaft 42. In one embodiment,the differential braking torque necessitates more force when turning thetilting shaft 42 in the counter-clockwise direction (e.g., when tiltingthe display 12 of FIG. 1 downward for viewing), and a proportionallylower force when turning the tilting shaft 42 in the clockwise direction(e.g., when tilting the display 12 of FIG. 1 upward against the wall W).For example, the weight of the display 12 is countered or offset by theincreased torque imparted to the tilting shaft 42 when rotating theshaft 42 in the counter-clockwise direction to tilt the display downwardfrom the wall W toward a seated observer; and when the display isreturned to its stowed position against the wall W by tilting thedisplay upward, less force is needed to turn the tilting shaft 42 backin the clockwise direction. The differential braking torque applied tothe tilting shaft 42 accounts for the weight of the display 12 as thedisplay 12 is tilted down, and thus has the effect providing equallybalanced downward/upward movement of the display 12. In this manner, thedifferential braking torque applied to the tilting shaft 42 provides theuser with a pleasant user-interface.

In one embodiment, the panel mount assembly 22 is movable relative tothe wall mount assembly 30 through at least four degrees of freedomincluding tilt, swing, pan, and telescope degrees of freedom. At leastthe tilt degree of freedom is dampened by a differential braking torqueapplied to tilting shaft 42. In one embodiment, all of the degrees offreedom are dampened by a differential braking torque applied to shafts28 and to tilting shaft 42.

In one embodiment, the link arm assembly 24 includes a first link armpanel 50 pivotably coupled to a second link arm panel 52 by hinge 54 bsecured to shaft 28 b, a second hinge 54 c coupled between first linkarm panel 50 and add-on bracket 32 and secured to shaft 28 c, and athird hinge 54 d coupled between the second link arm panel 52 and thetilting bracket 40 and secured to shaft 28 d.

The hinges 54 a, 54 b, 54 c, 54 d enable display mounting device 14 tomove through multiple degrees of freedom. For example, display mountingdevice 14 moves relative to the X-Y plane such that the link armassembly 24 telescopes away from the wall mount assembly 30, brackets44, 46 sway along the X-axis, brackets 44, 46 tilt around the X-axis,and brackets 44, 46 yaw in an arc around the Y-axis.

The link arm assembly 24 telescopes away from the wall mounting assembly20 along the Z-axis and is configured to collapse or fold in a nestedmanner such that the panel mount assembly 22 folds flat against the X-Yplane of the wall mounting assembly 20. In this manner, the displaymounting device 14 is configured to mount the display 12 to a wall orany other suitable surface where the display mounting device 14 includespan, tilt, swivel, swing/sway, and telescoping ranges of motions.

In one embodiment, the display mounting device 14 includes a dual-nestedpanel asymmetrical design that is characterized by the tilting bracket40 nesting with the second link arm panel 52, which folds flat againstthe first link arm panel 54 such that the panel mount assembly 22 nestsagainst/into the wall mounting assembly 20. In addition, the displaymounting device 14 has a low profile in which the panel brackets 44, 46retract to a stowed position that extends from the wall W (FIG. 1) byless than 3.4 inches, preferably by less than 2.4 inches away from thewall, and more preferably by about 1 inch away from the wall W.

FIG. 3A and FIG. 3B are cross-sectional views of two embodiments ofattachment mechanisms for shaft 28 b. In one embodiment, shaft 28 b isdampened by friction but does not include the differential brakingtorque provided to tilting shaft 42. The cross-sectional views are takenthrough the link arm panel 50.

In one embodiment illustrated in FIG. 3A, a U-shaped member 60frictionally fits around shaft 28 b and is coupled to the link arm panel50. The U-shaped member 60 includes opposing flanges 62, 64 that areconfigured to be fastened to the link arm panel 50 in a manner thatsqueezes U-shaped member 60 against shaft 28 b. In one embodiment, theU-shaped member 60 defines an inside height H and the shaft 28 b definesan outside diameter D, where the height H of U-shaped member 60 is lessthan the diameter D of the shaft 28 b. In this manner, when the U-shapedmember 60 is attached to the shaft 28 b, for example, via a lock screw,the shaft 28 b is tensioned or damped by the U-shaped member 60. Theshaft 28 b is tension-adjustable by selectively adjusting the attachmentforce of connectors attached between flanges 62, 64 and the link armpanel 50. The tension-adjustable link arm assembly 24 (FIG. 2) enablestranslation and rotation of the panel mount assembly 22 and the display12 (FIG. 1).

FIG. 3B is a cross-sectional view of another embodiment of the link armpanel 50 including a hook end 66 that frictionally fits around the shaft28 b. The hook end 66 includes an end portion 68 that is adapted to beselectively tightened against panel 50 to adjust a level of tension forthe shaft 28 b.

FIG. 3C is a perspective view and FIG. 3D is a side view of hinge 54 aincluding tilting shaft 42 selectively tensioned with a differentialbraking torque. It is to be understood that the hinge 54 a is generallycompatible with any of the panels 40, 50, 52, and any of the panels 40,50, 52 can be formed to provide differential torque to a respective oneof the shafts 28 b, 28 c, 28 d, or 42 (FIG. 2).

In one embodiment, the tilting bracket 40 (or panel 40) includes a base70 that terminates in a curved pad 72, and the hinge 54 a includes astrap 74 that secures tilting shaft 42 to the curved pad 72. In oneembodiment, the tilting shaft 42 defines an outside diameter (OD), andcurved pad 72 is formed to be substantially semicircular to have acurvature that is complementary to the OD of tilting shaft 42.

Hinge 54 a is configured such that strap 74 and curved pad 72 combine toprovide controlled torque that is delivered to tilting shaft 42 as panel40 is moved. Hinge 54 a has low inertia such that movement of the panel40 is accomplished with a moderately low force that need not overcomethe weight of the conventional massive tilting mechanisms.

Strap 74 is coupled to base 70 by an adjustment mechanism 76. The strap74 is configured to be tightened or loosened by adjustment mechanism 76to selectively adjust a level of braking torque delivered between curvedpad 72 and strap 74 to the shaft 28. In one embodiment, adjustmentmechanism 76 includes a screw 77 and a nut 78 that threads onto thescrew 77 to tighten/loosen strap 74 around a portion of shaft 28.Suitable materials for strap 74 include metals in general. In oneembodiment, strap 74 is fabricated from 301 stainless steel. It is alsoacceptable to fabricate strap from 302 stainless steel or fromAustenitic non-hardenable chromium nickel steel. In other embodiments,strap 74 is fabricated from heat treated steel or spring steel.

FIG. 3D illustrates an optional liner 80 provided between shaft 42 andcurved pad 72. The optional liner 80 provides a sacrificial bearing thatoffers some lubricity between the two contacting metals of shaft 42 andstrap 74 to minimize or eliminate galling between the metal strap 74 andthe metal shaft 42. Suitable materials for the liner 80 include polymerssuch as nylon, Teflon, or polyester or metal bushings such as brass,bronze, or stainless steel.

In one embodiment, the braking torque delivered to the shaft 42 by thecurved pad 72 and the strap 74 is a differential braking torque in whichthe rotational resistance delivered to the shaft 42 is different betweenthe clockwise and the counter-clockwise directions. For example, in oneembodiment, shaft 42 is provided with differential braking torque havinga clockwise braking torque T1 that is about 30% less than acounter-clockwise braking torque T2 (e.g., T1 is about 0.7T2). In oneembodiment, the clockwise braking torque T1 has a value between 0 to1200 pounds force-inch (lbs_(f)-in) and the counter-clockwise brakingtorque T2 has a value between −3900 to 0 lbs_(f)-in (the negative valueby convention represents counter-clockwise movement). Although it isdesired that the clockwise braking torque T1 be less than thecounter-clockwise braking torque T2, it is to be understood that forother applications the counter-clockwise braking torque T2 can be lessthan the clockwise braking torque T1.

In one embodiment, strap 74 is configured to be self-tightening in thecounter-clockwise direction, such that torsional rotation in thecounter-clockwise direction is met with a greater braking force thantorsional movements in the clockwise direction.

In one embodiment, the strap 74 applies a brake force to the tiltingshaft 42 to hold/maintain the tilting shaft at rest so the display 12stays where it has been positioned.

In one embodiment, only the tilting shaft 42 and its hinge 54 a isprovided with the differential braking torque. In another embodiment,each of the hinges 54 a, 54 b, 54 c, 54 d provides differential brakingtorque to its respective shaft 42, 28 b, 28 c, 28 d.

In one embodiment, the panels 40, 50, 52 are provided in a “clamshell”construction having two halves that move independently along a shaft. Inone embodiment, a multi-piece clamshell panel as illustrated in FIG. 2is formed that enables friction-damped link arm assembly 24 to extendand sway relative to wall mounting assembly 20 and panel mount assembly22. In addition, the clamshell structure enables display mounting device14 to fold flat against a wall (e.g., the stowed position) at a profiledistance of less than 2 inches, and preferably at a distance less thanabout 1 inch.

FIG. 4 is a side view of the display assembly 10. The display mountingdevice 14 is connected to the wall W by the connector 16. The display 12is connected to the panel brackets 44, 46 (one shown) and is configuredto telescope/extend away from the wall bracket 30, tilt up/down relativeto the wall W, swing left/right relative to the wall W, andtranslate/pan left and right along an arc.

The display 12 has been tilted down relative to the wall W on the axisof the tilting shaft 42 (the tilting shaft 42 has been rotated in thecounter-clockwise direction). In one embodiment, the tilting shaft 42 issubject to differential braking torque that is characterized by moreforce being called for to rotate the shaft 42 in the counter-clockwisedirection (compared to the clockwise direction). The greaterdifferential braking torque in the counter-clockwise direction isovercome by the weight of the display 12. Consequently, the user has thesensation that it is equally easy to tilt the display 12 down as it isto tilt the display 12 back up.

FIG. 5 is a side view of the display assembly 10 illustrating thedisplay mounting device 14 in a stowed position folded against the wallW. The display mounting device 14 provides a low-profile mount for theflat panel display 12. In one embodiment, the display mounting device 14is collapsible against the wall W such that the display 12 projects asmall distance L away from the wall W. In one embodiment, the distance Lis less than 3.5 inches, preferably the distance L is less than 2.5inches, more preferably the distance L is less than 1.5 inches. In oneembodiment, the distance L between the display 12 and the wall W isbetween about 0.5-1.5 inches.

The display mounting device 114 includes a wallmounting assembly 120 that is attachable to a wall or other surface byconnectors, a panel mount assembly 122 including the tilting shaft 42and the hinge 54 a (as described above) coupled to panel 140, and a linkarm assembly 124 coupled between the wall mounting assembly 120 and thepanel mount assembly 122.

In reference to FIG. 7, in one embodiment the link arm assembly 124includes a first link arm panel 150, a second link arm panel 152pivotably coupled to the first link arm panel 150 by hinge 154, a secondhinge 156 coupled between first link arm panel 150 and the wall mountingassembly 120, and a third hinge 158 coupled between the second link armpanel 152 and the panel 140 of the panel mount assembly 122. The firstand second link arm panels 150, 152 are configured to nest together whenthe display mounting device 114 is folded flat.

In one embodiment, at least the tilting shaft 42 is configured toinclude a differential braking torque. In general, the link arm panel152 is movable relative to the wall mounting assembly 120 through atleast four degrees of freedom including tilt, swing, pan, and telescopedegrees of freedom, and at least the tilt degree of freedom about thetilting shaft 42 is dampened by a differential braking torque.

In one embodiment, the display mounting device 114 includes asingle-nested panel asymmetrical design that is characterized by thesecond link arm panel 152 folding flat against the first link arm panel150 such that the panel mount assembly 22 nests against the wallmounting assembly 120.
